A framework and toolkit for the collection and analysis of QoS statistics for voice traffic in Next Generation Networks
(Telkom, 2000)The multi-service, multi-architecture nature of NGNs is so complex that the management of services, in addition to networks, emerges as a research challenge. Despite QoS limitations, VoIP (as opposed to VoATM), dominates ... -
An Internet paradigm approach to policy-based network management of legacy kit for VoIP services in Next Generation Networks
(Telkom, 2000)With QoS available on IP-dominant NGNs, Policy-based Network Management (PBNM) is an effective mechanism for managing services as opposed to actual devices. IP is ubiquitous, and any NGN must contend with legacy devices ... -
An Interoperable signaling solution for IP-based Next Generation Networks
(Telkom, 2000)Current VoIP signaling protocols are interoperable with the PSTN SS7 via H.323-to-SS7 or SIP-to-SS7 gateways. As we move toward the Next Generation Network, the PSTN falls away and we work toward carrier-grade VoIP ... -
Policy-based network management of legacy equipment in Next Generation Networks
(Telkom, 2001)Next Generation Networks use policy-based network management and QoS protocols to provide voice services on IP networks. Large numbers of older equipment still push IP packets. We present several solutions that include ...
